LUBRlCATlNG-CUP.

SPECIFICATION forming part of Letters Patent No. 412,206, dated October 1, 1889.

Application filed July 11, 1888. Serial No. 279,645. (No model-l To all whom it may concern.-

Be it kn own that 1, JOHN H. SHEPHEARD, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Lubricating-Cups, of which the following is a specification.

My invention relates to improvements in that class of lubricating-cups in which the flow of lubricant can be regulated by means of a valve, so as to either increase or diminish the quantity delivered from said cup as oooasion may require; and it consists of a vessel for containing the lubricant provided with a graduated scale and a screw-valve, by which the outlet-opening for the lubricant is governed, said valve havinga spring or dog which is fitted to engage in the graduations of the lubricant-vessel and retain the valve in its adjust-ed position against any liability of accidental derangement.

In the accompanying drawings, which are herein referred to and form part of this specification, Figure 1 is a side elevation of my lubricating-cup and its cover. Fig. 2 is a vertical section of the same through its central line, showing the screw-valve in elevation while raised from its seat. Fig. 3 is a like section with the screw-valve in its'closed position. Fig. 4 is a plan view of my lubricating-cup with the cover removed, and Fig. 5 is an enlarged and detached side elevation of the screw-valve with its head shown in vertical section.

As represented in the drawings, A is the cup or vessel for containing the lubricant, which is preferably made in cylindrical form, and is provided with a removable cap B,which is preferably fitted to attach to said cup by means of a closely-fitting slip-joint. Said cup is ordinarily provided with a screw-threaded nipple 1, for securing it in place, and with an outlet 2, through which the lubricant passes out of said cup, and the upper part of which forms avalve-seat for the valve that controls the flow of the lubricant. Said cup is also provided with a graduated scale 8, which is preferably formed in the upper edge of the cup as shown in Fig. 4b, and which by preference consists of a series of indentations formed in said upper edge. A crossbar 4. in the upper part of the cupA has a centrally-located screw-threaded opening formed therein to serve as a nut for a screw-threaded stem of the valve by which the flow of lubricant is regulated.

C is a valve, which is fitted to close on a seat in the outlet 2 of the cup A, and by which the flow of lubricant through said outlet can be regulated as occasion may require. The stem of said valve is provided with a screwthreaded portion 5, which fits in a screwt-hreaded opening in the cross-bar 4 (as in a nut) to produce an opening and closing movement of said valve in respect to.its valveseat. Said valve is also providedlwith a slotted head 6 at its upper end, and in said head is secured a spring 7, which, after projecting toward one side of the cup A, is bent backward toward the other side of the cup, and after passing freely through the slot in the head 6 the free end of said spring is bent downward to form a pendant 8, whose lower end is fitted to engage in the graduated scale 3. Said spring forms a cross-handle for the valve O, by which the latter can be 1nanipulated when the cap B is removed from the cup A.

A vent-hole 9 is made in the cap 13, either centrally, as shown in Figs. 2 and 3, or at any other convenient place above the upper edge of the cup A, for the purpose of admitting air into said cup above the level'of the lubricant, and thereby aiding the flow of the lubricant by reason of the atmospheric pressure acting thereon.

By making the cupA of a cylindrical form it can be readily cleaned to present an unblemished surface; but by so doing the usual means for screwing the cup in to its place is dispensed with, and to remedy this deficiency the interior of the cup must beprovidedwith some arrangement by which a wrench can be applied for the purpose of screwing the cup in place. To this end I preferably utilize the cross-bar 4, to which, when the spring 7 is ranged in line with said cross-bar, any 0rdinary wrench, like a screw-wrench or a forked wrench, can be applied to readily effect the purpose; but when preferred lugs or other projections 0r depressions may be formed in theinterior of the cup to serve alike purpose.

My lubricating-cup operates in the following manner: The cup A is charged with lubricant while the valve C is closed down to its seat, the cap B being of necessity removed for that purpose, and afterthe requisite opening through the outlet 2 has been ascertained to supply the required [low of lubricant through said outlet after each closure of said valve it can be quickly reset to its required position for producing the proper flow of the lubricant by the aid of the graduated scale 3, and when once set at theproper point the valve C will permit the required quantity of lubricant to feed through the outlet 2 so long as a supply of the lubricant is contained in the cup, or until the valve C is closed down to its seat for any purpose, and when the latter occurs the flow of lubricant ceases and all wastage thereof is entirely prevented.

I claim as my invention- A lubricating-cup consisting of a lubricant; receptacle having in its upper end a series of notches, a screw-valve fitted to govern the flow of lubricant from said receptacle, and a cap-piece which covers said receptacle and valve, the head of the stern of said valve be-
